Summary
A crane wire hoist rope failed during a standard lift, dropping the load, main block and wire approximately 3 m onto a wharf without injury. Examination identified ductile overload following internal corrosion. The flash recommends rope-specific maintenance informed by manufacturer input and risk assessment, and criteria for magnetic rope testing.
